These study materials are designed for undergraduate students of electrical engineering and
computing to complement the coursebook that is studied in class. We try to supply students
with additional texts and exercises believing that a larger language, especially lexical, input
can be nothing but useful for their further education.

Electrical Engineering Dictionary is a continually updated CD that provides workable definitions for practicing engineers. It serves as a reference and research tool for students and offers practical information for scientists and researchers in other disciplines. Areas examined include applied electrical engineering, microwave engineering, control engineering, power engineering, digital systems engineering, and device electronics.

Electric motors provide the driving power for a large and still increasing part of our modern industrial economy. The range of sizes and types of motors is large and the number and diversity of applications continues to expand. The computer on which this book is typed, for example, has several electric motors inside, in the cooling fan and in the disk drives. There is even a little motor that is used to eject the removable disk from its drive. All around us there are electrical devices that move things around. Just about everything in one’s life that whine, whirrs or...

semiconductors.In the first category are substances which provide an easy path for an electric current. All metals are conductors, however some metals do not conduct well. Manganin, for example, is a poor conductor. Copper is a good conductor, therefore it is widely used for cables. A non-metal which conducts well is carbon. Salt water is an example of a liquid conductor.
A material which does not easily release electrons is called an insulator. Rubber, nylon, porcelain and air are all insulator. There are no perfect insulators.

In industrialized countries, distribution systems deliver electricity literally
everywhere, taking power generated at many locations and delivering it to
end users. Generation, transmission, and distribution — of these big three
components of the electricity infrastructure, the distribution system gets the
least attention. Yet, it is often the most critical component in terms of its
effect on reliability and quality of service, cost of electricity, and aesthetic
(mainly visual) impacts on society....

Although there is no “typical” electric power system, a diagram
including the several components that are usually to be found in the
makeup of such a system is shown in Figure 1-1; particular attention
should be paid to those elements which will make up the component
under discussion, the distribution system.

This book is for people who want to learn basic electricity, electronics, and communications
concepts without taking a formal course. It can also serve as a classroom
text. This third edition contains new material covering acoustics, audio,
high-fidelity, robotics, and artificial intelligence.

Engineering for sustainability is an emerging theme for the twenty-first century,
and the need for more environmentally benign electric power systems is a critical
part of this new thrust. Renewable energy systems that take advantage of
energy sources that won’t diminish over time and are independent of fluctuations
in price and availability are playing an ever-increasing role in modern power
systems.

Electricity is an invisible force that is used to transfer
energy into heat, light, intelligence, or motion. Electricity
is explained in terms of electrical charge, potential differ-
ence (or voltage), electrical charge flow (or current), and
resistance to current flow. Figure 1-1 graphically illus-
trates electron flow through a conductor by comparing it
with water flow through a pipe. The normal unit of current
measurement is the ampere, whereas the normal unit of
voltage measurement is the volt. The unit of opposition to
current flow, or resistance, is the ohm...

Experienced product designers are increasingly expected to be adept at incorporating a range of components into their designs. Students and experimenters too need to look beyond basic circuits and devices to achieve adequate design solutions. For those experienced in engineering design, this is the guide to electric motors.

This guide has been written for electrical Engineers who have to design, select electrical equipment, install these equipment and, inspect or maintain low-voltage electrical installations in compliance with international Standards of the International Electrotechnical Commission (IEC). “Which technical solution will guarantee that all relevant safety rules are met?” This question has been a permanent guideline for the elaboration of this document.
